ABSTRACT:
A full-color image forming apparatus has a cooling fan switchable between rotating speeds of “full speed” and “half speed.” A transfer portion thermistor is installed near a photosensitive drum and an intermediate transfer member, and a printer control portion controls the rotating-speed switching of a cooling fan based on the temperature detected by the transfer portion thermistor. The printer control portion sets the rotating speed of the cooling fan at “half speed” when print job is started, sets a fan speed switching threshold value at 30° C. during the print job of only the single-side printing, sets the fan speed switching threshold value at 25° C. during a duplex print job, and switches the cooling fan to “full speed” when the detection temperature is higher than the set fan speed switching threshold value.
